                    Changes between version 5.4.0 and 5.4.1
                    =======================================


Improvements
=============

* A warning has been added for 1./x and 1.\x syntax clarification.

* A new output argument has been added to regexp function to retrieve
  subpatterns matches. See SEP #86.

* New xmlName function added to retrieve the name of a XML element.

* clc(): New icon in the toolbar to clear the console. See bug #12049.

* test_run no longer takes into account skipped tests in the summary.
  See bug #12117.

* Two new commands added:
 - For SciNotes:
     scinotes modules/core/macros/whos.sci
       Opens a file.
       If the file does not exist, SciNotes proposes to create it.
     scinotes -indent modules/core/macros/whos.sci
       Allows to indent automatically a Scilab file.

 - For Xcos:
     xcos modules/xcos/examples/integral.xcos
       Opens the integral Xcos schema.
       If the file does not exist, Xcos proposes to create it.

* Search is now possible in the console. Shortcut F3 or CTRL+F enables it.
  See Bug #11841.

* editvar proposes direct save to the CSV format of the whole variable or the
  selection.

* Completion in Scilab is now case insensitive. See bug #6320.

* variance is now vectorized and allows the syntax variance(x,"*",w).
  See bug #12362.

* Console command history is now stored in SCIHOME/history file under all platforms.

* In Scilab documentation, 'scilab:needs-examples="no"' tag has been added to specify
  that the help page does not need example.



Xcos
=====

* New Flowmeter block in the thermohydraulics palette added to measure a
  thermohydraulics flow.

* Palette icons and some blocks rendering improved.

* xcosPalGenerateAllIcons function added as a Xcos palette utility function.

* New ODE solver added: LSodar. Automatically switches methods to efficiently
  solve both stiff and nonstiff problems. It includes a rootfinding feature.

* Two new fixed-size step ODE solvers added: Dormand-Prince 4(5) and Runge-Kutta 4(5).
  Added to the CVode package, they also benefit from the rootfinding feature.

* Implicit fixed-size stop ODE solver added: Implicit Runge-Kutta 4(5).
  Added to the CVode package, it also benefits from the CVode rootfinding feature.

* Block parameter errors (types and sizes) reporting improved.

* Some scopes blink on simulation avoided.



Compilation
============

* Enforce a minimal version of Flexdock (1.2.3).

* Enforce a minimal version of JLaTeXMath (1.0.2).

* Enforce a minimal version of Scirenderer (1.1.0).

* Enforce a minimal version of XMLGraphics (1.4).

                    Changes between version 5.3.3 and 5.4.0
                    =======================================

Scilab Desktop
===============

* Thanks to this new feature, Scilab confirms its usability and its strong
user-oriented approach. Scilab desktop is the new concept behind Scilab
windows management taking advantage of our docking system (advanced FlexDock features).
Out of the box, Scilab is now able to save all windows layouts including the
help browser, the variable browser, the command history, SciNotes and Xcos.
Through this major improvement, position and size of all windows are
saved from a session to another.

* A file browser component has been developed and fully
integrated into Scilab desktop and all other components have been improved
to provide the best user experience for Scilab users.

* Editvar has had important refreshment. It allows plot and subplot, manages
almost all Scilab variable types and is much more faster.

* Scilab desktop provides various predefined layouts:
 - Simple      The standard Scilab console
               => Scilab 5.3.3 (and previous versions) defaults.
 - Integrated  The variable browser, the history browser and the file browser
               are opened by default and combined around Scilab
               console to provide an ergonomic workspace.
               => Scilab 5.4.0 defaults

* Variable browser has been improved:
 - The dimension of the variable is shown by default.
 - The variable browser table is automatically resized when docked.
 - A tooltip has been added on the type column to display the name of the type.
 - A tooltip has been added on the size column to display the size in bytes
  (like in previous versions of Scilab).
 - Refresh is automatical (See Bug #9446).

* A unique Preferences window has been developed to configure Scilab and its modules.
This unique interface can be launched using preferences() function.


Graphics
=========

* Entire refactoring of Scilab graphic capabilities in order to solve the known issues
  of graphical cards compatibilities and many Scilab crashes.

* Based on SciRenderer (rendering library based on JoGL), Scilab graphics have
  been rewritten to provide new graphic functionalities with:
  - better performances,
  - better stability,
  - 2-D zoom using the mouse wheel,
  - new 3-D zoom capabilities,
  - rotation available through the mouse right-click.
  SciRenderer is a free and open source library developed by Scilab Enterprises
  for 2-D and 3-D rendering of scientific data.

* Improved graphic exports:
  - Off-screen export (Scilab will not open a window to export with driver).
  - New bitmap formats supported: PNG, JPEG and BMP in the driver function.
  - New vectorial formats supported: PDF and SVG in the driver function.
  - Many portability issues fixed.

* Obsolete value for line_style property:
  0 and 1 are equivalent values for SOLID rendering.
  A warning message will be displayed if the user tries to set this property to 0.
  Setting this property to 0 will no more be supported in Scilab 5.4.1.

* datatips tool improved on several aspects:
  - It is now possible to manage directional arrows as well as
    square mark markers.
  - The automatic label placement has been improved to avoid the
    overlapping with the curve.
  - It is now possible to have painted box or box free labels.
  - Markers can now be selected and moved using the arrow keys
    or deleted with the "Del" key.

  - uimenus now appear as 'Children' of this handle when they are added to the
    console,
  - the 'ShowHiddenHandles' property enables the user to make some hidden
    graphic objects visible.

* Scilab Console and graphic figure menus are now uimenus. They are hidden by
  default. To see them in the children list, use set(get(0), "ShowHiddenHandles", "on")

* New uicontrols added:
  - 'image' style uicontrol: display, transformation and various other
    operations on images.
  - 'table' style uicontrol: display data in a table form (read-only).

* The 'Value' property can now contain non-integer values and allows to take full
  advantage of 'slider' style uicontrols (See bug #7380).

* Figure resizing can now be managed by the user (uicontrol position setting, ...)
  through the 'resizefcn' property.


CLI Console (GNU/Linux and Mac OS X only)
==========================================

* Wide characters supported.

* Multiline command supported.

* Command line display improved.

* List of shortcuts in NW/NWNI mode:
  - CTRL+W removes the previous word.

            the line.
  - UP or Ctrl+P recalls the previous line.
  - DOWN or Ctrl+N recalls the next line.
  - TAB for completion. Scilab displays a list of all names (functions, variables) that
    start with the characters already typed by the user.
  - Ctrl + A or HOME moves the cursor to the beginning of current line.
  - Ctrl + B or LEFT moves the cursor one character to the left.
  - Ctrl + D or DELETE deletes the current character.
  - Ctrl + E or END moves the cursor to the end of command line.
  - Ctrl + F or RIGHT moves the cursor one character to the right.
  - Ctrl + H or BACKSPACE deletes the previous character.

Arnoldi Package
================

* New function:
  - eigs function added (See SEP #82).


Elementary Functions
====================

* New functions:
  - dec2base function added (See SEP #75).
  - nthroot function added (See SEP #78).

* linspace and logspace deprecate the use of non-integer values as third input argument.

Sparse
======

* qmr function updated and modified.
   Calling qmr(F, Fp, x) where F is a function returning A*x
   and Fp a function returning A'*x is deprecated.
   Use qmr(F, x) instead where F prototype is
   function y = F(x, t)
   [...]
   endfunction
   where t is used to make F return A*x or A'*x.
   Same behavior has been implemented for qmr( ..., M1, M1p, M2, M2p).
   See qmr help page for examples and details.


Scilab
======

* save/load functions can export/import Scilab data to SOD format:
 - Scilab data are saved and loaded using a standard, HDF5-based, documented,
   and fully tested: Scilab Open Data format (SOD).
 - Graphic handles can be saved under the SOD format.
 - 'save' writes data to HDF5 format when using new calling sequence
   save("filename.sod", "a", "b", "c"). This format is Scilab 6 compatible.
 - 'save' displays a message when using old calling sequence
   save("filename", a, b, c) and writes data in old Scilab binary format.
   This format will not be supported by Scilab 6.
 - The 'matfile2sci' function now converts MAT-files to SOD files.

* Calling load with a file descriptor as first input argument is now obsolete.
  Please replace the file descriptor by the corresponding file name.
  This feature will be removed in Scilab 6.0.0.

* Update the default size of the Scilab stack to 100 million elements (instead of
  50M). See stacksize help page for more information.

* Scilab Desktop provides a button in dockbar to get the help about the component.

* External modules are managed out of the box by test_run function. See bug #9834.
Example: test_run('SCI/contrib/toolbox_skeleton')

Tests
======

* The assert module provides a set of assertion functions.
  The goal of this module is to provide functions to check the
  behavior of some other functions, for example in unitary tests.
  We emphasize the use of consistent tools for testing numerical
  issues, with the goal of testing numerical algorithms more easily.
  In particular, we provide a comparison function for two floating
  point numbers, which allows to check that two numbers are
  "numerically almost equal", i.e. that the relative error is small.
  This automatically fixes Bug #4381.

* A fourth argument added to test_run to export test results to XUnit format.

* A new function called example_run has been introduced, this function tests the
  examples given in Scilab help pages. See SEP #83.

  In this case, the file association will not be configured.

* ATOMS module is now mandatory and is installed in the minimal installation.


Performances
=============

* Under GNU/Linux and Mac OS X, Scilab start-up speed of scilab-cli and
  scilab-adv-cli has been improved by 15 to 20 % (see Compilation for more
  information).

* SSE is now enabled by default under GNU/Linux with 32-bit CPU (it is already
  the case under 64-bit CPU).
  Pentium III class (or equivalent) with SSE instructions is required.

* Improved performances of pareto_filter function (Genetic algorithms).

* 'hank' function performances improved.

* Using api_scilab, construction of any type of lists is now much faster (300x in some cases).

Compilation
============

* Under Windows, Scilab uses VS 2010 Pro and Express solution.

* Under GNU/Linux and Mac OS X, engine libraries have been merged into a single
  library named libscilab-cli.so. This greatly improves the start-up
  performances.
  Note that the --enable-maintainer-mode enables the previous behavior (simply
  the development process).

* Under GNU/Linux and Mac OS X, all modules build as standalone their algorithms
  as a static library (only available in the source tree).
  This will avoid an important dependency tree for unitary testing.

* Under GNU/Linux and Mac OS X, for each module, the list of
  explicit dependencies on the other libraries is no more needed.
  Use libscilab-cli.so or libscilab.so to link against Scilab.

* Scilab dependency on Java HDF has been removed.

* Enforce a minimal version of JRosetta (1.0.4).

* Enforce a minimal version of flexdock (1.2.0).

ATOMS
======

* 'atomsQuit' function added to allow to call .quit of modules loaded by ATOMS
  when user closes Scilab session. See SEP #77.

========

* Java mapping of Scilab data has now a new method called getType() which
returns the value of the ScilabTypeEnum enum.

* New methods added:
  - Scilab.execException(String)
    Same as Scilab.exec(String) but returns an exception when a Scilab error occurs
  - Scilab.execException(String[])
    Same as Scilab.exec(String[]) but returns an exception when a Scilab error occurs

Obsolete Functions
===================

* 'oemtochar' and 'chartooem' functions (windows_tools) are obsolete and will be
   removed in Scilab 5.4.1.

* 'showalluimenushandles' function (graphics) was undocumented. This function is
  obsolete and will be removed on 5.4.1.
  Use set(get(0), "ShowHiddenHandles", "on"); instead.

* 'code2str' and 'str2code' are obsolete and will be removed on 5.4.1, please use
  'ascii' instead.

* config function is now obsolete and will be removed in Scilab 5.4.1.
  Please use 'preferences' instead.

* dnaupd, dneupd, dsaupd, dseupd, znaupd and zneupd deprecated for eigs.

* createpopup and uipopup functions are now obsolete. Please use 'uicontextmenu' instead.


Removed Functions (previously declared as obsolete)
====================================================

* ilib_for_link, ilib_build no more accept files with ".o" or ".obj" extensions
  for source files.

* 'with_atlas' removed. Please use 'getdebuginfo' instead.

* C API function Error(x) removed. Please use SciError instead.

* 'MSDOS' removed. Please use 'getos' instead.


Known Incompatibilities
========================

* In previous versions, modulo(x,0) and pmodulo(x,0) returned x. But this solution is
  not correct. Indeed, the expression used to compute the modulo is x - y * int(x / y)
  for the modulo function and x - y * floor(x / y). Now, they return an error and
  %nan with ieee(2). See bug #7216.

* In previous versions, newest function could be called with a string vector
  as second (up to last) input argument. In these cases, only the first string of
  the vector was taken into account. These calls now return an error. See bug #11398.

* Setting the "foreground" property for a figure was possible even if it was not
  officially supported or documented. An error is now returned.
  Please use the axes "foreground" property instead. See bug #11369.

* getcallbackobject: Input argument must be an UID (String) and no more an index (Constant).


Known Issues
=============
* Some issues at start-up under Mac OS X 10.6.7 (and previous 10.6 versions)
  have been reported.
  If you have "Audio Hijack" installed on your Mac OS X, it prevents some
  applications to work including Scilab. See Bug #7012.
  Uninstall / disable Audio Hijack should fix this problem.
  Airfoil, also developed by Rogue Amoeba, has been reported as also breaking
  Scilab.

Known Incompatibilities
=======================

* In previous versions, modulo(x,0) and pmodulo(x,0) returned x. But this solution is
  not correct. Indeed, the expression used to compute the modulo is x - y * int(x / y)
  for the modulo function and x - y * floor(x / y). Now, they return an error and
  %nan with ieee(2). See bug #7216.

* In previous versions, newest function could be called with a string vector
  as second (up to last) input argument. In these cases, only the first string of
  the vector was taken into account. These calls now return an error. See bug #11398.

* Setting the "foreground" property for a figure was possible even if it was not
  officially supported or documented. An error is now returned.
  Please use the axes "foreground" property instead. See bug #11369.


            Changes between version 5.4.0-alpha-1 and 5.4.0-beta-1 of Scilab
            ================================================================


Graphics
========

* Entire refactoring of Scilab graphic capabilities in order to solve the known issues
  of graphical cards compatibilities and many Scilab crashes.

* Based on SciRenderer (rendering library based on JoGL), Scilab graphics have
  been rewritten to provide new graphic functionalities with:
  - better performances,
  - better stability,
  - 2-D zoom using the mouse wheel,
  - new 3-D zoom capabilities,
  - rotation available through the mouse right-click.
  SciRenderer is a free and open-source library developed by Scilab Enterprises
  for 2-D and 3-D rendering of scientific data.

* Improved graphic exports:
  - Off-screen export (Scilab will not open a window to export with driver).
  - New bitmap formats supported: PNG, JPEG and BMP in the driver function.
  - New vectorial formats supported: PDF and SVG in the driver function.
  - Many portability issues fixed.


* Bug #4289 fixed - Graphic exports were not working when the drawlater or the
                    pixmap modes were activated.

* Bug #4339 fixed - listvarinfile did not manage graphic handles.

* Bug #4818 fixed - Scilab could not export graphics which contained a lot of information.

* Bug #6582 fixed - A copy of a handle did not keep foreground property.

* Bug #6644 fixed - New graphic windows take care of default figure properties (uimenu).

* Bug #7998 fixed - %h_get failed on heterogeneous handle matrix.

* Bug #8241 fixed - Graphical properties were not always inherited.

* Bug #8250, #10567, #10614 fixed - Artefacts dropped on the
                                    vectorial (EPS/PDF/SVG) exports.

* Bug #8705 fixed - Some specific graphics could not be saved.

* Bug #8916 fixed - Menu to export in PS format was missing in graphic figures.

* Bug #9721 fixed - Documentation improved on tight_limits. Thanks to Samuel
                    Gougeon.

* Bug #10240 fixed - In a Scilab localized in French, SVG export could use "," instead
                     of "." for numerical separator.

* Bug #10290 fixed - Error message for bad assignement of interp_color_vector updated.

* Bug #10360 fixed - Default format for export is now PNG instead of BMP.

* Bug #10365 fixed - To copy a handle to a figure (instead of an axes) crashed Scilab.

* Bug #10395 fixed - xset("clipping", [1,2,3,4]) returned an error.

* Bug #10417 fixed - xget("background") returned a wrong value.

* Bug #10637 fixed - xs2svg crashed when first input argument was not a figure handle.
                     An error message is now displayed.


GUI
===

* A 'Console' handle has been created and can be obtained by calling get(0):
  - uimenus now appear as 'Children' of this handle when they are added to the
    console,
  - the 'ShowHiddenHandles' property enables the user to make some hidden
    graphic objects visible.

* Scilab Console and graphic figure menus are now uimenus. They are hidden by
  default. To see them in the children list, use set(get(0), "ShowHiddenHandles", "on")

* New uicontrols added:
  - 'image' style uicontrol: display, transformation and various other
    operations on images.
  - 'table' style uicontrol: display data in a table form (read-only in Scilab
    5.4.0-BETA-1 version).

* The 'Value' property can now contain non-integer values and allows to take full
  advantage of 'slider' style uicontrols (See bug #7380).

* Figure resizing can now be managed by the user (uicontrol position setting, ...)
  through the 'resizefcn' property.


Scilab
======

* save/load functions can export/import Scilab data to SOD format:
 - Scilab data are saved and loaded using a standard, HDF5-based, documented,
   and fully tested: Scilab Open Data format (SOD).
 - Graphic handles can be saved under the SOD format.
 - 'save' writes data to HDF5 format when using new calling sequence
   save("filename.sod", "a", "b", "c"). This format is Scilab 6 compatible.
 - 'save' displays a message when using old calling sequence
   save("filename", a, b, c) and writes data in old Scilab binary format.
   This format will not be supported by Scilab 6.
 - The 'matfile2sci' function now converts MAT-files to SOD files.

* Calling load with a file descriptor as first input argument is now obsolete.
  Please replace the file descriptor by the corresponding file name.
  This feature will be removed in Scilab 6.0.0

* Update the default size of the Scilab stack to 100 million elements (instead of
  50M). See stacksize help page for more information.

* Scilab Desktop provides a button in dockbar to get the help about the component.

* External modules are managed out of the box by test_run function. See bug #9834.
Example: test_run('SCI/contrib/toolbox_skeleton')


XML
===

* xmlClose renamed in xmlDelete and xmlGetOpenStreams in xmlGetOpenDocs.

* Bug #10185 fixed - Add xmlDelete("all") in xml.quit.

* Bug #10594 fixed - size could not be used with two arguments on XMLList.

* Bug #10630 fixed - Typo fixed in an error message.

* Bug #10670 fixed - Crash avoided when xmlRead had an argument with a bad size.

* Bug #11250 fixed - Avoid a crash when an error is met during xmlValidation.


Documentation
=============

* Management of Docbook tags <note>, <caution>, <warning>, <important> and
 <tip>. See bug #10505.

* Function help_skeleton extended to suggest the <revhistory>, <latex>, <note>,
  <caution>, <warning>, <important> and <tip> tags in examples.

  - Wrong calling sequences
  - Errors in examples
  - Bad formatting
  - Typos


Dynamic Link
=============

* DEBUG_SCILAB_DYNAMIC_LINK was not available under GNU/Linux or Mac OS X.
  See bug #11142

Xcos
====

* Major performance improvements on the simulation start-up. On important diagrams,
  the gain is very important (from minutes to milliseconds). See bug #8188.

* Performance improvements on diagram saving/loading.

* A compressed file format is now available (ZCOS) and allows more flexibility on
  data format.

* Ports styles and labels are now available to external modules.

* New examples are provided in the help pages of the following blocks:
  - ABS_VALUE - Absolute value
  - EVTDLY_c - Event delay
  - AFFICH_m - Display value
  - CLSS - Continuous state-space system
  - SELECT_m - Selector block
  - NEGTOPOS_f - Threshold negative to positive

* HDF5 is now a mandatory dependency of Scilab (even in a minimal build)

* Bug #11060 fixed - ccache use can be disabled with --disable-ccache .


Elementary Functions
====================

* New functions:
  - dec2base function added (See SEP #75)
  - nthroot function added (See SEP #78)

* linspace and logspace deprecate the use of non-integer values as third input argument.

* The toeplitz macro is now vectorized.


Sparse
======

* qmr function updated and modified.
   Calling qmr(F, Fp, x) where F is a function returning A*x
   and Fp a function returning A'*x is deprecated.
   Use qmr(F, x) instead where F prototype is
   function y = F(x, t)
   [...]
   endfunction
   where t is used to make F return A*x or A'*x.
   Same behavior has been implemented for qmr( ..., M1, M1p, M2, M2p).
   See qmr help page for examples and details.


CLI Console (GNU/Linux and Mac OS X only)
=========================================

* Wide characters supported.

            the line.
  - UP or Ctrl+P recalls previous line.
  - DOWN or Ctrl+N recalls next line.
  - TAB for completion. Scilab displays a list of all names (functions, variables) that
    start with the characters already typed by the user.
  - Ctrl + A or HOME moves the cursor to beginning of current line.
  - Ctrl + B or LEFT moves the cursor one character to the left.
  - Ctrl + D or DELETE deletes the current character.
  - Ctrl + E or END moves the cursor to the end of command line.
  - Ctrl + F or RIGHT moves the cursor one character to the right.
  - Ctrl + H or BACKSPACE deletes the previous character.
  - Ctrl + K kills command line from cursor to the end.

            Changes between version 5.3.3 and 5.4.0-alpha-1 of Scilab
            =========================================================

Scilab Desktop
===============

* Thanks to this new feature, Scilab confirms its usability and its strong
user-oriented approach. Scilab desktop is the new concept behind Scilab
windows management taking advantage of our docking system (advanced Flexdock features).
Out of the box, Scilab is now able to save all windows layouts including the
help browser, the variable browser, the command history, SciNotes and Xcos.
Through this major improvement, position and size of all windows will
be saved from a session to another.

In this context, a file browser component has been developed and fully
integrated into Scilab desktop and all other components have been improved
to provide the best user experience for Scilab users.

Editvar has had important refreshment. It allows plot and subplot, manages
almost all Scilab variable types and is much more faster.

Scilab desktop provides various predefined layouts:
 - Simple      The standard Scilab console
               => Scilab 5.3.3 (and previous versions) defaults.
 - Integrated  The variable browser, the history browser and the file browser
               are opened by default and combined around Scilab
               console to provide an ergonomic workspace
               => Scilab 5.4.0 defaults


XML Features
=============

* Version 5.4.0 introduces XML management features. It allows easy access to
XML files, validation and writing.

 - XMLObjects - Describe the properties of the different XML objects
 - xmlAddNs - Add a namespace to a XML Element
 - xmlClose - Close a XML document
 - xmlDTD - Create a XML DTD object
 - xmlDocument - Create a new XML document
 - xmlDump - Dump a XML object
 - xmlElement - Create a new XML element
 - xmlFormat - Format a Scilab variable into XML
 - xmlGetNsByHref - Get a namespace by its href
 - xmlGetNsByPrefix - Get a namespace by prefix
 - xmlGetOpenStreams - Get all open XML documents or all open XML Validation files.
 - xmlNs - Create a new XML Namespace
 - xmlRead - Read a XML stream from a local or distant file
 - xmlReadStr - Read a XML tree from a string
 - xmlRelaxNG - Create a XML Relax NG object
 - xmlSchema - Create a XML Schema object
 - xmlValidate - Validate a document in using a DTD, a Relax NG or a Schema.
 - xmlWrite - Write a XML document in a file
 - xmlXPath - Make an XPath query on a XML document
 - xmlIsValidObject - Test the existence of a XML object

Those features have been developed in the context of the OASIS R&D project.

New Functions
=============

* The assert module provides a set of assertion functions.
  The goal of this module is to provide functions to check the
  behavior of some other functions, for example in unitary tests.
  We emphasize the use of consistent tools for testing numerical
  issues, with the goal of testing numerical algorithms more easily.
  In particular, we provide a comparison function for two floating
  point numbers, which allows to check that two numbers are
  "numerically almost equal", i.e. that the relative error is small.
  This automatically fixes Bug #4381.

* The damp function in CACSD module computes the natural pulsation
  and damping factor of linear dynamical systems.

Performance
============

* Under GNU/Linux and Mac OS X, Scilab start-up speed of scilab-cli and
  scilab-adv-cli has been improved by 15 to 20 % (see Compilation for more
  information).

* SSE is now enabled by default under GNU/Linux with 32-bit CPU (it is already
  the case under 64-bit CPU).
  Pentium III class (or equivalent) with SSE instructions is required.

Compilation
============

* Under Windows, Scilab uses VS 2010 Pro and Express solution.

* Under GNU/Linux and Mac OS X, engine libraries have been merged into a single
  library named libscilab-cli.so. This greatly improves the start-up
  performances.
  Note that the --enable-maintainer-mode enables the previous behavior (simply
  the development process).

* Under GNU/Linux and Mac OS X, all modules build as standalone their algorithms
  as a static library (only available in the source tree).
  This will avoid an important dependency tree for unitary testing.

* Under GNU/Linux and Mac OS X, for each module, the list of
  explicit dependencies on the other libraries is no more needed.
  Use libscilab-cli.so or libscilab.so to link against Scilab.

* Enforce a minimal version of JRosetta (1.0.4).

* Enforce a minimal version of flexdock (1.0).

* Enforce a minimal version of GIWS (1.3.0).

* Force the Java class version target to version 6 (or 1.6).

* Add Java 7 in the Debian & Ubuntu search path under GNU/Linux.

* Under GNU/Linux and Mac OS X, if ccache is installed, use it to build Scilab.

* Bug #9409 fixed - Warning "remark #8291" removed with Intel Fortran 2011 compiler.

* Bug #9500 fixed - Explicit the GUI module manifest class-path to facilitate Debian

                    under 64-bit platform.


Variable Browser
=================

* Shows the dimension of the variable by default.

* Automatically resize the variable browser table when docked.

* A tooltip has been added on the type column to display the name of the type.

* A tooltip has been added on the size column to display the size in bytes
  (like in previous versions of Scilab).


History
========

=========

* Obsolete value for line_style property:
  0 and 1 are equivalent values for SOLID rendering.
  A warning message will be displayed if the user tries to set this property to 0.
  Setting this property to 0 will no more be supported in Scilab 5.4.1.

* getcallbackobject: Input argument must be an UID (String) and no more an index (Constant).

* datatips tool improved on several aspects:
  - It is now possible to manage directional arrows as well as
    square mark markers.
  - The automatic label placement has been improved to avoid the
    overlapping with the curve.
  - It is now possible to have painted box or box free labels.
  - Markers can now be selected and moved using the arrow keys
    or deleted with the "Del" key.

Known Issues
============
* Random crash under Mac OS X at start-up.
  Some random crash can occur at first Scilab start-up. Try to restart Scilab.

* Some issues at start-up under Mac OS X 10.6.7 (and previous 10.6 versions)
  have been reported.
  If you have "Audio Hijack" installed on your Mac OS X, it prevents some
  applications to work including Scilab. See Bug #7012.
  Uninstall / disable Audio Hijack should fix this problem.
  Airfoil, also developed by Rogue Amoeba, has been reported as also breaking
  Scilab.
